Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information.

LibHTML: Add LayoutNode classes for "display: list-item" and its marker This patch removes the hard-coded hack for "display: list-item" from LayoutBlock and adds LayoutListItem and LayoutListItemMarker. Elements with "display: list-item" now generate a LayoutListItem, which may then also generate a LayoutListItemMarker if appropriate. :^)

LibWeb: Rename LayoutNode classes and move them into Layout namespace Bring the names of various boxes closer to spec language. This should hopefully make things easier to understand and hack on. :^) Some notable changes: - LayoutNode -> Layout::Node - LayoutBox -> Layout::Box - LayoutBlock -> Layout::BlockBox - LayoutReplaced -> Layout::ReplacedBox - LayoutDocument -> Layout::InitialContainingBlockBox - LayoutText -> Layout::TextNode - LayoutInline -> Layout::InlineNode Note that this is not strictly a "box tree" as we also hang inline/text nodes in the same tree, and they don't generate boxes. (Instead, they contribute line box fragments to their containing block!)

LibWeb: Rename LayoutNode::render() to paint() "Paint" matches what we call this in the rest of the system. Let's not confuse things by mixing paint/render/draw all the time. I'm guilty of this in more places.. Also rename RenderingContext => PaintContext.

LibWeb: Make the ListItemMarkerBox index-aware. In the ListItemBox we get the index of the current <li> element in the parent and pass it to the ListItemMarkerBox. This patch is work towards #2059

LibWeb: Position the ListItemMarkers according to their width Previously they were positioned with a fixed offset. However this lead to wider markers with more than one character to collide with the element itself. Now the ListItemMarkerBox generates and stores the appropriate String in its constructor and sets its own width according to that. The ListItemBox then lays out the Marker taking this width into account. This also made the painting a lot easier since we don't generate the needed Strings every time we repaint, just once.
